IIVIPIROV'IEIMIIIN'I' IN' IlaATEI-IVIACHIIIEI.

The Schedule referred to in thella Iletters Patent and. making part. ofthe Same To all iolbom, it mag concern Be it known that I, Wlin'InnB.NOYES, of Manchester, in the county of Hillshorongh, and State of NewIziampshire, have invented certain new and useful Im,- provements inLath-Machine and 1 do hereby declare that the following is a full,clear, and exact description thereof, reference being had to theaccompanying drawings, and tothe letters of reference marked thereon,which form a part of this specification.

The nature of my invention consists in the con struction and generalarrangement of alath-cutting machine, hy which a series of laths may becut from one piece of lumber at the same time.

In order to enable others slcilled in the art to which my inventionappertains, to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawings,in which-Figure l is a side elevation, and

Figure 2, a plan view, and

Figure is a view of the under roller, showing its ilanges andprojec'tions.

A represents the frame Of the machine, made of any suitable size andheight, such that the operator can stand alongside of thesame, and. feedthe lumber on the top.

Immediately under the top of the frame A, in suitable journal-boxes,runs the main shaft B, said shaft extending on one side beyond theframe, and is at this end provided with a pulley, O, which, by a belt orother suitable means, is connected with the engine or motive-power.

Upon the shaft B is keyed a series of saws D D, placed at regularintervals, and projectingthrongh the table or top of the frame.

This prtion l l of the saw-table is slotted or provided with a series ofslots, at equal distances apart,

through each of which one of the saws D passes.

Directly in front of the saws D D, and in suitable journal-boxes inthesides of the frame A, is placed a shaft or roller, Gr, which runstransversely across the frame, and projects the least possible distanceabove the upper surface of the top of the frame, through a slot in thesame. The roller Or shaft Gr is corrugated longitudinally,for a suitabledistance around its entire Surface, forming sharp edges or teeth for thepurpose of catching and feeding the board, from w-hich the laths are tobe cut, to thesaws.

Above the journals of the roller Gr are verticallyslotted standards H H,in which are placed boxes I I, forming the hearings for another rollerJ, which runs above and parallel with the corrngated roller Gr.

l`he journal-boxes I I are pressed dowmvard by Spiral Springs tt a,operated upon by set-sorews b 7), in such a, manner that the roller Jcan by this means be placed as close as necessary to the roller Gr, andstill yield sufficiently for the lumber to pass between said rollers,the upper roller pressing the lumber against the sharp edges on thelower roller, so that when said lower roller Gr revolves, it may carrythe; board along with it. It will readily b seen, that by' this meansthe rollers can be adjusted to any thiclrness of lumber.

In like manner are placed in rear Of the saws D D, two rollers, K and L,between which 'the laths, when cut, or as they are being cut, arecarried out.

Both of these rollers are provided with series ofcircular flanges, c c,placed at equal distances apart, and directly in rear of the saws, thatis, each tlange on the lower roller K, is directly in rear of one of thesaws, and the flanges on the upper rollerL are directly by a belt, f, isconnected with a wheel, M, on a Shaft,

N, in the lower part of the frame A.

The shaft N is provided with a pulley, g, which, by a belt, 71, isconnected 'with the `wheels 0 and P, upon the ends of the rollers Gr andK respectively, and thus the required rotary motion is communicated' tosaid rollers. The wheel M is placed loosely upon the shaft l`,

and a feathered collar, It, is thrown in and out of gear' with the same,by means of the pivoted lever S, so that the operator can at any timestop the motion of the feeding-meehanism without stopping the motion ofthe saws.

Upon the table or top of the frame A. is` placed a' guide, T, againstwhich the board is laid before being caught by the feeding-roller Gr.

This guide is adjustalole, it being provided with an arm, lc, whichmoves in loops m m, as seen in Iig. 2..

Upon a pin on the top of the frame A is pivoted a lever, W, the inner orrear end of which is provided with an clongated slot, and passed overa'pin or bolt on the arm l, by which means the sliding guide Toan bemoved out or in at pleasure.

A spring, placed under the lever W, presses its outer or front endagainst a rack-bar, X, under which it passes, .so as to hold the leverat any point desired.

The saws D D are all lreyed firmly on a line on the shaft B, andtheinteeth are arranged, as shown in the drawing, even or on a line, sothat they can be hled at the same time, Without removing the saws fromthe shaft, or removing the Shaft from its bearin 8 In the slots, uponthe portion 1 3, of the frame A, are

Piaced. suitable preiections, which form guides between l of the arm lc,loops M 771, lever W, land rack-bar X,

which the-saw t eetil pass so as to preserve their edgres substautiaiiya s and for the purposes lrerein set fortir,

and prevent them from bending. V 3.
